A static "method" is just a regular function that is attached to a class. This is useful when it belongs to that class semantically, and in extreme cases necessary in an inheritance hierarchy. The class name provides a visual namespace for accessing the function, e.g. Map.from does something different than Set.from.
However, you would only ever do that when you already have an existing class. You would never create an empty class only to put a static method inside it. In such a case, a simple object literal with a regular object method suffices:
const MyObject = {
myFunction() {
console.log('foo');
},
};
MyObject.myFunction();

The static keyword defines a static method or field for a class, or a static initialization block (see the link for more information about this usage). Static properties cannot be directly accessed on instances of the class. Instead, they're accessed on the class itself.

What are your thoughts on Static Methods?
There is an easy way out with JS/TS, Dart, etc. Just use a top-level function which you export as well. Java is different because everything must be inside some class. I guess static methods are kinda nice if you want to mirror some Java API or whatever. It makes porting code a bit easier. More on reddit.com

September 26, 2017Static method in class is recognised as a function, but when called it returns undefined
To answer your question about what static methods actually look like without the syntactic sugar: class MyClass { method1() { // do stuff } static method2() { // do other stuff } } is equivalent to function MyClass() { } MyClass.prototype.method1 = function () { // do stuff }; MyClass.method2 = function () { // do other stuff }; More on reddit.com

August 17, 2018Concretely, what is the purpose of static method in es6 ?
It provides methods related to classes and class instances that don't necessarily require a class instance to be used. Note that these have existed before ES6. ES6 only added the static keyword used to create static methods when using the class syntax. A common use case is factory functions. These functions are used to create instances in ways contrary to normal construction. You can see these in JS builtins like: Array.from() Object.create(, ) Promise.resolve() Other, similar examples are utility functions that generate data relating to that type Number.parseInt(, ) Date.now() They can also be utilities for obtaining information about instances Array.isArray() Object.getOwnPropertyDescriptor(, ) Note that, as static methods, these operations can be run against values that may not be instances of that type. For example Array.isArray() wouldn't be very useful as an instance method only available to Array instances. More on reddit.com

Mostly for namespacing. Imagine you need 10 functions of related feature. Instead of taking up 10 names from global scope, using static methods you use just one global name, being the class name.
Remember that apps often end up being complex, using 3rd party libraries. Name clashes is a real problem when complexity comes to play.

Does this apply to JavaScript?
Static methods usually indicate a method that doesn't know where it belongs. It is sitting out there trying to belong to the class it is on, but it doesn't really belong, because it doesn't use the internal state of the class. When we look at our classes from the Single Responsibility Principle (SRP) viewpoint, a static method is usually a violation because it tends to have a responsibility that is not the same of the class it is attached on.

I use static methods for class simplification, and external inheritance. For a class simplification example, this is a piece of a vector class I wrote: export default class Vector { constructor({ x, y }) { this.x = x; this.y = y; } // ... a bunch of methods. static getZero() { return new this({ x: 0, y: 0 }); } static fromArray([x, y]) { return new this({ x, y }); } } Its far easier to call Vector.getZero() than to call new Vector({ x: 0, y: 0 }), or even to import a new file called createZeroVector() over an over. It makes more sense to keep the generation simplification of a class as a part of the class itself. This also allows you to extend and inherit these functions with much more ease. As for external inheritance, I don't know if there is a better way to do this, but I've also used static methods to achieve something like this: class Parent { constructor({ a, b }) { this.a = a; this.b = b; } static defaultOptions = { a: 0, b: 0, }; static create(options = {}) { return new this({ ...this.defaultOptions, ...options, }); } } class Child extends Parent { static defaultOptions = { a: 1, b: 2, }; } // child will have this.a === 1 and this.b === 2. const child = Child.create(); Which would let you easily create defaults for your class.

In object-oriented programming, a static method is a method that is associated with a class, rather than an instance of the class. In JavaScript, static methods are defined using the static keyword and they can be accessed without creating an instance of the class.
